Broccoli packs a surprising nutritional punch. Many people know it for vitamins and fiber. But how much protein does it really offer? A cup of broccoli provides about 2.6 grams of protein. This comes from raw, chopped broccoli florets. Cooked versions offer slightly less, around 2.1 to 2.5 grams per cup. These numbers make broccoli a solid plant-based protein source.
This article dives deep into broccoli’s protein content. We explore measurements, comparisons, and health benefits. You’ll learn why this green veggie deserves a spot in your meals.
Understanding Broccoli Serving Sizes
A standard cup equals 8 ounces or 236 milliliters. For broccoli, one cup typically means 91 grams of raw, chopped florets. This is the USDA standard. Steamed broccoli weighs about 156 grams per cup due to water absorption.
Protein amounts vary by preparation. Raw broccoli has 2.6 grams per cup. Boiling reduces it to 2.1 grams. Steaming keeps it at 2.5 grams. Always check labels or use a food scale for precision.
Broccoli’s protein includes essential amino acids. It scores well for plants. A cup delivers 5% of daily needs for adults on average.
Detailed Protein Breakdown
Let’s break down the nutrition. One cup of raw broccoli (91g) contains:
- Calories: 31
- Protein: 2.6g
- Carbs: 6.6g
- Fiber: 2.6g
- Fat: 0.3g
Boiled broccoli (156g per cup) has:
- Protein: 2.8g (slightly higher due to denser packing)
Note: Density changes with cooking, but per 100g, it’s consistent at 2.8g.
Per 100 grams, broccoli offers 2.8 grams of protein regardless of cooking method. This makes it reliable. Data comes from USDA FoodData Central, a trusted source.
Broccoli protein is complete when paired with grains. Alone, it provides leucine, isoleucine, and valine effectively.
Why Broccoli Protein Matters
Plants like broccoli shine for protein. Vegans and vegetarians benefit most. A cup covers 5-10% of daily protein needs. Adults need 46-56 grams daily. Three cups hit 7.8 grams toward that goal.
Protein aids muscle repair, satiety, and metabolism. Broccoli’s version supports these without excess calories. It’s low-fat and cholesterol-free.
Studies show plant proteins reduce heart disease risk. A 2023 meta-analysis in Nutrients linked cruciferous veggies to better outcomes. Broccoli fits perfectly.
Comparing Broccoli to Other Veggies
Broccoli leads in protein among common vegetables. Here’s a quick comparison per cup (raw, chopped):
- Broccoli: 2.6g
- Spinach: 1.7g
- Kale: 2.2g
- Brussels sprouts: 2.6g (tie)
- Cauliflower: 2.0g
Broccoli edges out most. It beats potatoes (2.5g cooked) and carrots (0.9g). For density, it’s top-tier.
Legumes like lentils offer more (18g per cup cooked). But broccoli wins for low-calorie diets. Pair it with quinoa for a protein boost.
| Vegetable | Protein per Cup (g) | Calories per Cup |
|---|---|---|
| Broccoli | 2.6 | 31 |
| Spinach | 1.7 | 7 |
| Kale | 2.2 | 33 |
| Brussels Sprouts | 2.6 | 38 |
| Cauliflower | 2.0 | 25 |

Boosting Protein with Broccoli Recipes
Incorporate broccoli easily. Steam it for salads. Add to stir-fries. Blend into smoothies.
Try this simple recipe: Broccoli Protein Stir-Fry. Sauté 2 cups broccoli with tofu and quinoa. Yields 15g protein per serving. Quick and tasty.
Roast broccoli with olive oil and nuts. One cup roasted gives 3g protein plus healthy fats.
Soups work too. Puree broccoli with beans. A bowl delivers 10g protein.
These methods preserve nutrients. Overcooking leaches some protein, so keep it crisp-tender.
Health Benefits Beyond Protein
Broccoli fights inflammation with sulforaphane. This compound activates detox genes. One cup provides 81mg vitamin C—over 100% daily value.
It supports eye health via lutein. Bone strength comes from vitamin K (116% DV per cup). Fiber aids digestion.
Antioxidants lower cancer risk. Harvard studies link regular intake to reduced odds.
For weight loss, broccoli shines. High volume, low calories fill you up. Protein enhances fullness.
Maximizing Protein Absorption
Eat broccoli raw or lightly cooked. Heat denatures some protein but improves digestibility.
Combine with vitamin C sources. Broccoli already has plenty. Pair with peppers for synergy.
Digestive enzymes in raw form aid breakdown. If bloated, steam first.
Myths claim cooking destroys protein. False—it’s stable. A 2022 Journal of Food Science study confirms minimal loss.
Broccoli in Diets Worldwide
In Vietnam, broccoli grows in Khanh Hoa. Local farms supply fresh heads. Phan Rang markets offer it cheap and organic.
Asian cuisines stir-fry it with soy. Mediterranean diets steam with lemon. Adapt to your style.
Global data shows rising broccoli consumption. USDA reports 10% yearly increase.
Sustainability and Protein
Broccoli uses less water than meat. Producing 1g protein from beef needs 50 times more resources. Broccoli wins for planet-friendly eating.
Organic options reduce pesticides. Choose local for freshness.
